or carbonated beverage previously prepared and stored close by and incommunication with the fountain itself with or without the addition ofsyrup fiavorings.

In the accompanying drawings, Figure 1 is a sectional elevation throughthe aeratedliquid-measuring chamber of the fountain, and Fig. 2 is aplan view of same. Fig. 3 is an elevation, to a larger scale, of thebracket carrying the lever for actuating the outlet-valve; Fig. 4, aplan view of this lever and bracket. Fig. 5 is a side elevation of thefountain, showing one of the syrupmeasuring chambers in section. Fig. 6is a plan view with the fountain removed. Fig. 7 is a front elevation ofthe fountain and syrup-valves. Figs. 8 and 9 are detail views, to anenlarged scale, of the tappet-rod for actuating the syrup-valves. Fig.10 is a perspective view of the handle, showing the sliding latch.

The fountain itself may stand on a pedestal or base or may have asidebracket to allow it to be secured to thes'ide of the counter orice-box.

Dealing first with the action of the fountain itself, a measuredquantity of aerated liquid is run into its interior, the top pressure ofthe gas is let off, or shifted, and the aerated liquid then flows outinto a glass or other vessel, these three operations of filling,shifting, and discharging being eifected by the rocking action of asingle lever or handle, which actuates the inlet, snifting, and outletvalves.

1 is the aerated-liquid-meastiring chamber of the fountain, preferably astrong glass cylinder held between an upper disk 2 and lower disk 3.These disks are provided with lugs 4, through which pass bolts or stays5 to hold the disks in position, the joints between the glass cylinderand the disks being made by leather or rubber washers. The upper disk 2carries a bearing 6, through which and the forked ends 7 of thehand-lever 8 is threaded a pin 9, so that the lever may rock thereon. Ina plane at right angles to the axis of the pin!) are arranged the axesof the three valves 10, 11, and 12. The inlet-valve 10, controlling theadmission of aerated liquid through the pipe 13 to the cylinder, isnormally held to its seating 14 on the under side of the lower disk 3 bymeans of a strong spring 15 and the pressure of the aerated liquid, andits spindle 1 6, guided in the upper and lower disks, is extended andcontinued through a gland 17 in the upper disk. The shifting-valve 12 issimilarly normally held to its seating 18 on the under side of the upper,disk by the spring 19, its spindle 35 passing through the guide 20. Theoutlet-valve 11 is placed in the center of the lower disk and isnormally held to its seating 21 by its own weight; but the closing ofthe two valves may be rendered more certain by weighting, the spindle 22or by the action of a compression-spring 23 between the upper disk and acollar 24 on the spindle. The lower head 25 of the shifting- Valve isarranged on the full opening of the valve to depress the arm 26-of asmall rocking. lever pivoted at 27"to a bracket 28, carried by two feet28 from the under side of the upper disk. The other arm 29 of this leveris forked, as shown in Fig. 4, and bears against a stop 30 on the collar24. The valvehead 25 is clear ofithe arm'26 when the valve is closed andonlybeginsto operate the rocking lever when the 'valve 12 has beenopened some distance. As the fulcrum 27 is nearer to the snifting-valvehead than the stop 30, a small amount of travel of the valve-head willcause the valve 11 to lift a proportionatelyincreased amount. The upperor working surfaces of the rocking leverare curved, so that the fartherthe snifting-valveis pushed down or opened the greater the proportionalincrease of movement given to the outletvalve becomes. The collar 24 ispreferably valve 11 turning while being lifted and lowered. Thevalve-spindle 22 is guided in the upper disk and also in thedelivery-nozzle 31,

and means 32 are provided for adjusting the position of the valve alongthe axis of its spindle. Bridge-pieces 33 34, fixed between the forks ofthe handle, open the valves 10 and 12 by depressing their respectivevalvespindles l6 and 35. It will thus be seen that on raising the handle8 the bridge-piece 33 depresses the spindle 16 and opens the inletvalve10 against the pressure of the spring 15, admitting the aerated liquidinto the cylinder 1, which partly fills, forming a cushion of air andgas in the upper part of the cylinder. The handle 8 is then lowered,allowing the spring 15 to close the inlet-valve. The bridge-piece 34then depresses the spindle 35 and opens the snifting-valve 12 and allowsthe confined air and gas to pass out into the atmosphere by theexhaust-pipe 54. On further depressing the handle the valve-head 25bears upon the rocking lever-arm 26, cansing the forked arms 29, actingon the stops 30, to lift the outlet-valve, and the aerated liquid thenflows out quietly.

When it is desired to flavor the aerated liquid, the fountain isprovided with the syrup apparatus, as shown in Figs. 5, 6, and 7. Inthis apparatus I provide two syrupmeasuring chambers 36 and 37,preferably fixed one on each side of the fountain, and they are soarranged that a measured quantity of the syrup fiows into thedelivery-nozzle 31 together with the aerated liquid, the nozzle being atthis point widened out in order that they may be more thoroughly mixed.As the required proportion of aerated liquid is much greater than thatof syrup and since the syrup is of such a nature that its movement iscomparatively slow,the flows of the proportionate amounts of syrup andaerated liquid practically take place in the same time. Thesyrup-measuring chamber 37 is provided with inlet and outlet valves 38and 39, respectively, rigidly connected by the distance-piece 40, sothat each movement of the valves opens one passage and closes the other.These valves consist of rubber or leather washers, preferablycone-shaped and fixed by screws to the distance-piece, the whole beingcapable of sliding in a groove in the bottom of the measuring-chamber,which is cylindrical in shape and in two parts jointed at 41. The syrupflows into the measuringchambers 36 and 37 from the syrup-reservoirs 43through passages 42, controlled by the valve 38 and a correspondingvalve in chamber 36. that when not in use the outlet-passage is closed,and the measuring-chamber is therefore'full and ready to discharge atthe next operation. On top of the syrup-measuring chamber I provide asmall-bore air-pipe 44, reaching to the top of the syrup-reservoir toallow the air to escape andthe syrup to rise in the tube at each fillingof the chamber, so that the differences in the amount of syrup delivereddue to the continual lowering of tthe surface in the reservoir will bevery mi- I preferably arrange the valves so and 47, with the spindle 46,forming a kind of bell-crank lever. The lower end of the springtappet-rod 48 is pivoted to the external arm 47, the upper end beingattached to the latch 49, pivoted to the casing 50 and normally helddown by the tension-spring 51. Each of the reservoirs andmeasuring-chambers is provided with its own latch and tappet-gear, asliding bolt 52 in the handle-forks being arranged to slide under andengage either of the latches at the choice of the operator.

The cycle of operations is as follows: The handle 8 is first raised, theinlet-valve 10 being thereby opened and a supply of aerated liquidadmitted into the cylinder 1. The handle is now depressed, whensimultaneously with the opening of the snifting-valve 12 the syrup inletand outlet valves 38 39 are respectively shut and opened by means of thebolt 52, latch 49, tappet-rod 48, and bell-crank 47 45. On furtherdepression of the handle the outlet-valve 11 is opened by means ofrock-lever 26 29, the issuing streams of aerated liquid and syrupmingling in the enlarged chamber 31 and passing out through the nozzle.

The object of the spring 53 in the tappetrod 48 is to permit of varyinglifts of the latch 49 without straining the valve, as would be the caseif the connection were positive.

\Vhen the apparatus is not in use, the weight of the levers, tappet-rod,&c., and the pressure of the syrup tend to keep the valve 39 closed, andthe chamber is therefore always full atthe beginning of each operation.

The whole of the contrivance is mounted on a marble or walnut cabinet,asusually provided, and one fountain may be used for every two sweeteneddrinks.

In my apparatus the measuring-chambers are fixed close up to thefountain, thus taking up little room, and all the working gear is at theback of the chambers and almost hidden, so that two, three, or four setsof these machines can be arranged Without appearing cumbersome.

Having now fully described my invention, what I claim, and desire tosecure by Letters Patent, is I 1.
